| DESCRIPTION OF THE INSTRUMENT | |
| Type Of Measure | Composite Index |
| Brief Description |
The Mean Overall Index for Rheumatoid Arthritis (MOI‐RA) combines single measures into an overall continuous measure of RA disease activity. It includes the mean of standardized values of tender and swollen joint counts (28‐, 42‐, or 66/68‐joint counts), patient global assessment of disease activity (PtGA) on a 10‐cm visual analog scale (VAS), patient assessment of pain on a 10‐cm VAS, provider global assessment of disease activity (PrGA) on a 10‐cm VAS, Health Assessment Questionnaire (HAQ), and erythrocyte sedimentation rate (ESR; range 0–100). |

| PRACTICAL APPLICATION | |
| Method of administration | Physician |
| Recommendations to score |
The mean of the standardized values is calculated producing a range for the MOI‐RA between 0 and 100. All components are standardized to range from 0–100. VAS for PtGA, patient assessment of pain, and PrGA each range from 0–100. ESR values >100 are replaced by the value 100. HAQ values ranging from 0–3 are multiplied by 100. If values of 1–3 components are missing, standardized values are calculated from the available component values and the mean of the standardized values is recorded. |
